What is the situation for these two equations ×=10+2 and 10x=2
Tom [10]

Answer:

1 is x=12

2 is x= 1/5

Step-by-step explanation:

For equation number 1 you just add 10 and 2, which is 12.

For equation number 2 you divide 2 by 10 and simplify it to 1/5. So x = 1/5

Please help me please! I’m stuck, and I can’t figure this out. Please include the form in your answer! No phony answers pls!
nevsk [136]

Answer:

x ≈ - 6.74, 0.74

Step-by-step explanation:

x² + 6x - 5 = 0 ( add 5 to both sides )

x² + 6x = 5

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 5 + 9

(x + 3)² = 14 ( take square root of both sides )

x + 3 = ± \sqrt{14} ( subtract 3 from both sides )

x = - 3 ± \sqrt{14}

Then

x = - 3 - \sqrt{14} ≈ - 6.74 ( to the nearest hundredth )

x = - 3 + \sqrt{14} ≈ 0.74 ( to the nearest hundredth )

8. Find the congruence transformation that maps ∆ABC to ∆A’B’C’. Explain your reasoning
puteri [66]
The transformation is a reflection on the y-axis. 

If we take the y-axis as the mirror line as shown in the diagram below, we can see that the distance of vertices A, B, and C to the mirror line are equals to the distance of vertices A', B' and C' to the mirror line.

The initial population of a town is 3600​, and it grows with a doubling time of 10 years. What will the population be in 8 ​year
shutvik [7]
If is doubles in 10 years, then you should divide 2 by 10 to get the yearly growth rate equaling 1/5. Multiply 1/5 by 8 equals 8/5= 1 3/5. multiply that number by 3600, giving you 5,760.
